Problem is if light is coming in the FRONT then the light passes through the image 
layer TWICE. Just look at your wristwatch from the side under a relatively direct 
source of light to see this.

ESCAPING through the back?

Is it? Wouldn't it be better to use reflected light so the 'intensity' of light coming 
off the panel is proportional to ambient light?

Its not power that rotates the LCs, its electric field. And the intensity of that 
field effectively determines how far on or off each pixel is in terms of blocking 
light. Remember, the LCs don't emit any light, they only block light coming from the 
backlight or (in the case of reflective screens) light going in both directions.
